Improvement of the wild carrot by grafting it on the cultivated carrot
L. DANIEL (Compt. Rend. Acad. Sci. Paris, 127 (1898), No. 2, pp. 133-135).

The author reports the results of grafting the wild carrot upon a well-known variety of cultivated carrot having red roots. The stock exerted an influence not only upon the scion itself, but also upon the seedlings of the scion. The seedlings presented anomalies in the number and form of the cotyledons, the young plants from the grafted wild carrot were larger, greener, and less villous than those from the ungrafted wild carrot—i.e., in general intermediate between the wild and cultivated carrot. As the plants became older some of them followed the spreading habit of the wild carrot and others the erect habit of the cultivated carrot. The roots were white, like those of the wild carrot, but with a diameter from 2 to 3 times that of the latter and from one-fourth to one-third that of the cultivated carrot. Out of 30 plants from the grafted carrot 8 ran to seed the first season, an occurrence which, though fairly common in the cultivated carrot, is very rare in the wild carrot. The author believes that these results demonstrate the possibility of improving wild plants by grafting, followed by an intelligent selection of the offspring of the scion.
